[From end-organ disease to a classifiable bladder pain syndrome: paradigm shift in the understanding of urological pain syndromes exemplified by the condition currently called interstitial cystitis].
Growing clinical and scientific data imply that the condition currently called interstitial cystitis is not just a mere bladder end-organ disease but that the symptoms perceived to be related to the bladder are rather one aspect of a complex pelvic pain syndrome. The term bladder pain syndrome/interstitial cystitis (BPS/IC) suggested by the European Society for the Study of IC/PBS (ESSIC) for this condition is currently the only one strictly consistent with the taxonomy guidelines of the European Association of Urology and the International Association for the Study of Pain. BPS would be diagnosed on the basis of chronic pelvic pain, pressure, or discomfort perceived to be related to the urinary bladder, accompanied by at least one other urinary symptom such as persistent urge to void or urinary frequency. Confusable diseases as the cause of the symptoms must be excluded. Classification of BPS types might be performed according to findings at cystoscopy with hydrodistention and morphologic findings in bladder biopsies. The end-organ condition interstitial cystitis has thus become a chronic pain syndrome with a predominantly neurovisceral pathophysiology. In daily practice, therapeutic approaches aiming at both the peripheral bladder urothelium and central nervous targets should be combined. A multimodal treatment strategy, such as the combination of tricyclic antidepressants with instillation therapy, still appears reasonable and justified.
